SPECIFICATION forming part of Letters IPatent No. 896,974, dated January29, 18189.

Application filed May 29, 1888. Serial No. 275,420. (No model.)

To all whom, it may concern:

Be it known that I, EDWARD BARRATH, of

Cincinnati, in the county of Hamilton and State of. Ohio, have inventedcertain new and useful Improvements in (foal-Ilods, oil? which thefollowing is a specification.

The object of my invention is to provide a novel eoal-hod or similarvessel wherein the to the accompanying drawings, making a part of thisspecification, inwhich Figure 1 is a central. vertical section of acoal-hod embodying my invention. Fig. 2 is a similar view of amodification thereof. Fig. 3 is a diagram re n'esenting the first stepof bonding the metal; Fig. l, a similar view showing the second step;Fig. 5, a similar view showing the third step, and Fig. (i a similarview showing another step in the process of. con.- structing thecoal-hod.

In the drawings, the letter A indicates the conical-shaped body of thebucket, 15 the baserim, and the bottom. The preferred form ofconstruction is .to make the double hooks o Z) of the scam in thebase-rim l3, and the oporation of constructing a seam is as follows: Themetal from which the rim is formed is first bent inward and upward, intothe shape shown in Fig. 3, by means of a spinning tool or by dies. It isthen bent into the shape shown in Fig. l. The lower edge of the body Ais then placed on the ledge (Z in the manner shown in Fig. Pressure thenapplied to the parts i and (Z by means of dies or other 40 b, restingon. the bottom 0, as shown in Fig. 1.

Thus the bucket is formed with a doublehooked seam, a b, in the upperhook, I), of which the bottom G rests, and in the lower one, a, of whichthe flange c of the body A rests. compression of the double hooks a b.This is the preferred method of uniting the parts together. It isevident that the form shown in Fig. 2 could be made by forming the metalof the body A with the double hooks a I), as described with reference tothe base-rim 13. The bottom (I is shown slightly depressed or concave,so as to stiffen the bottom and prevent the vilnfation of the metal, andthus increase the wear of the bed.

What I claim is A coal-hod or similar metallic vessel, consisting of thebody A, the rim B, and the bottom 0, each made out of a single piece ofmetal and united by a double-hooked seam formed of a double hookintegral with one of the parts, into the two hooks of which double hookthe other parts are respectively inserted and clamped, substantially asshown and de scribed. 4

In testimony whereof I have hereunto set my hand.
